Annele Virtanen
Head of Aerosol Physics Research Group, University of Eastern Finland
I received my PhD in Tampere University of Technology (TUT, Department of Physics) 2004. After that I continued working as a postdoc and group leader at TUT. On January 2012 I moved to University of Eastern Finland (UEF) to lead the Aerosol Physics Laboratory. I have a strong background in measurement method development and applications related to atmospheric aerosols. My major research questions are related to the atmospheric aerosols: how they form, what are their properties and what is the role they play in the Earth’s climate through their interactions with water vapour. To study these questions in a comprehensive way I have established a wide international collaborative networks and consistently developed our own research infrastructure at UEF.
